Siril - Bug Fix for MacOS Ventura users

Bug Fix for MacOS Ventura users

By Cyril Richard

MacOS Ventura is the thirteenth major version of macOS, released recently. Currently, Siril cannot be executed correctly on it because it is impossible to use the mouse on the application. This bug, which is very annoying, is caused by low-level changes in Ventura that affect GTK, the library that manages the graphical interface of Siril. And all applications using GTK3 are affected by this bug, namely GIMP v2.99, RawTherapee, Inkscape, Darktable and many others…

Currently we are able to provide a version of Siril with a partial fix on GTK. This allows the user to use the mouse again, but there may be other downsides. Of course, we will keep you informed about the progress of this issue.

In the meantime, I invite you to go to the Download page and download the version of Siril corresponding to the architecture of your Apple computer. These versions are brought by our new macOS maintainer, René de Hesselle.

Thank you Rene very much for the bug fixes for MacOS Ventura! I was unable to downgrade back to the previous OS, so this fix allows me to continue to use Siril. I really appreciate it !


Have there been others who have tested the bug fix with this new solution? I appreciate the work that was done to solve the bug. Thanks.

I am using it right now with OS 13.1 Ventura. Works great!

I also have Venturer13.1 and whilst it works, the mouse function isn’t perfect. I find that often an item requires clicking twice before it responds. Better than it was thought. Well done for making it useable.
